Let's divide 25378848 by 129
Let's see how many times 129 fits into 25378848.

Let's proceed to step 1:
2 divided by 129 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 129

Moving on to step 2:
129 can be fit into 25 0 times, resulting in a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Include the next digit (3) from the dividend after 25, then repeat: 253 / 129

Let's proceed to step 3:
If we divide 253 by 129, we get 1 and a remainder of 124.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 129 from 253 to get 124.
Bring next digit (7) of the dividend behind the 124 and repeat the process: 1247 / 129

Moving on to step 4:
If we divide 1247 by 129, we get 9 and a remainder of 86.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Subtract 1161 from 1247 to get 86.
Fetch the next digit (8) from the dividend, attach it to 86 and continue: 868 / 129

On to step 5:
129 goes into 868 6 times with a remainder of 94.
Use 6 as the next digit of our solution. 
Result so far: 196.0
If we subtract 774 from 868, we get 94.
Fetch the next digit (8) from the dividend, attach it to 94 and continue: 948 / 129

Advancing to step 6:
When dividing 948 by 129, we get 7 with a remainder of 45.
Use 7 as the next digit of our solution. 
Result so far: 1967.0
The remainder is 45 after subtracting 903 from 948.
Fetch the next digit (4) from the dividend, attach it to 45 and continue: 454 / 129

Going ahead to step 7:
129 can be fit into 454 3 times, resulting in a remainder of 67.
Record the quotient 3 as the next digit in the result. 
Result so far: 19673.0
The remainder is 67 after subtracting 387 from 454.
Append the next digit (8) from the dividend to 67 and continue with: 678 / 129

On to step 8:
When dividing 678 by 129, we get 5 with a remainder of 33.
Put 5 as the next digit of the answer. 
Result so far: 196735.0
If we take 645 away from 678, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 9:
The number 129 fits into 330 2 times, leaving a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 196735.2
If we subtract 258 from 330, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 10:
If we divide 720 by 129, we get 5 and a remainder of 75.
The next digit of our result is 5. 
Result so far: 196735.25
Subtract 645 from 720 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 11:
750 divided by 129 is 5 with a remainder of 105.
Record the quotient 5 as the next digit in the result. 
Result so far: 196735.255
If we subtract 645 from 750, we get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

The final outcome is 196735.255, with a leftover of 0.0105.
